W205 Transmission and Front and Rear Differential Fluid Change

I have a 2016 C300 with 80k. I am changing the transmission fluid/filter, then the differential fluids.
1) I was told that there is no need to change the Transfer Case Fluid because it's mixed/shared with the transmission fluid. Can someone confirm ?

Fluid Spec should be 236.15 and takes about 6 quarts if you are not draining the Torque Converter.

2) Should I drain the torque converter fluid as well or simply follow the following video:

for changing Fluid on a 722.9 transmission ? if there is a sperate service for the transmission that involves draining the torque converter, then, can someone provide instructions for it ?
3) Looking for detailed instructions on how to change the Front and Rear Differential Fluid on a W205.
So far, I gathered the following:

Front Differential Fluid MB part number is 001989880311 (Buy 1 litter, takes about .8 - not sure how to check fluid level)
Rear Differential Fluid is 75w80 (Buy 1 litter, takes about .8 - not sure how to check fluid level)
Not sure if the front and rear are actually different fluids, however, that's what MB Parts provided.
Fill Plug on the Front Differential is hard to reach and saw in a video that you can fill it from the drain plug but some fluid will spill out. Video Link:

(should this method be followed or is there a better way ? )
